Description
Technical field
The present invention relates to a kind of heat exchanger for the automobile that is particularly suitable for use in, above-mentioned heat exchanger has at least one aluminium alloy heat exchange
Pipe and at least one and component for being connected of heat exchange pipe fluid, wherein above-mentioned heat exchanger tube and component in the form of integral solder each other
It is connected.The present invention, which is additionally related to a kind of aluminium alloy or the aluminium strip with the core layer being made of the aluminium alloy, to be used to manufacture weldering
The collecting pipe of the heat exchanger connect or the purposes of tube sheet, further relate to a kind of rolling clad aluminum band for being particularly suitable for aforementioned applications
Production method.
Background technology
The effect of heat exchanger is heat energy from a kind of media flow is transferred to another media flow.In order to reach this
Purpose, heat exchanger has at least one heat exchanger tube, and the purpose for adding above-mentioned heat exchanger tube is the first media flow circulation in use,
Above-mentioned media flow is thermally contacted by heat exchanger tube with second of media flow.In addition, heat exchanger tube especially can be with second in use
Plant media flow and surround and stream.In order to reach preferably heat-transfer effect, heat exchanger is generally constructed to provide having greatly for heat exchange
Imitate heat exchange area.In order to reach this purpose, heat exchange coil can be used, multichannel heat exchanger tube and/or with multiple heat exchanger tubes
Heat-exchanging tube bundle.Extraly or alternately can also be by some cooling bodies, such as fin be welded on heat exchanger tube, with further
Increase thermocontact area.
In addition at least one heat exchanger tube, heat exchanger also has other components, and operationally a kind of media flow can be from
Said modules are flowed out, and are flowed into heat exchanger tube, or a kind of medium is flowed into said modules from heat exchanger tube.These are connected to
Also cried media flow to be incorporated into heat exchanger tube or received the component of the media flow flowed out from heat exchanger tube heat exchanger tube one end
Do collecting pipe or tube sheet.Collecting pipe is appreciated in particular that as the object of an all round closure, typically tubulose above-mentioned object, which has, to be used
With the hole being connected with heat exchanger heat-exchanging tube.Tube sheet refers in particular to the object that surrounding is not fully closed, such as horizontal with half of pipe
Section, and by miscellaneous part, such as plastic plate completion turns into the object of an all round closure.Tube sheet, which also has, to be used for and heat exchanger
The connected hole of heat exchanger tube.
The corrosion of the welding heat exchanger generation affected by environment of aluminum can produce very big problem, particularly with automotive field
Application.
Because for the single component of heat exchanger, such as fin, heat exchanger tube, collecting pipe generally make for respective purpose
With the aluminium alloy with different chemical compositions and corresponding different corrosion potentials optimized, so can occur coupling in heat exchanger
The bimatallic corrosion system of conjunction.
Usual such case will embody in selection, and reason is such as thin-walleds in some especially important component,
The pipeline that stream has medium uses the aluminium alloy for having relatively preferable corrosion potential, and less important for those heat exchanging devices
Component, such as fin then makes of the aluminium alloy for having bad corrosion potential.So those hardly important are changed in use
Hot device assembly is corroded at first, it is possible thereby to the service life of heat exchanger is improved, namely until the time of leakage appearance.
Flat tube is extruded using multi-cavity as far as possible for the refrigerant pipe in cooling agent network on the compressor of air-conditioning, i.e., it is so-called
MPE.In order in MPE manufacturing process limit extruding force size, compared with other heat exchanger assemblies used it is usual with
Rolled alloy based on alumal (EN-AW 3xxx types alloy), the typical aluminium alloy used in MPE is typically containing less
Alloying element (such as manganese, silicon or copper).
This component such as collecting pipe or tube sheet that is particularly suitable for use in, said modules pass through the company of welding with MPE in heat exchanger
Connect.Therefore MPE corrosion potential is smaller than collecting pipe or tube sheet in many cases, so MPE preferably with collection
Corrode in region between the weld and first layer air fin of pipe.
In order to avoid many kinds of counter-measures known to this MPE local corrosion, above-mentioned measure can also be used in combination sometimes：
It is known that addition contains spelter coating on MPE, such as by thermal spraying or by coating the fluxing oxidant layer containing zinc.
On MPE surfaces, coating zinc can locally reduce the corrosion potential of aluminum, and thus corrosion can be preferentially in side parallel to pipeline table
Face is formed.Local corrosion, i.e., so-called spot corrosion, can be limited in this way, to significantly improve the use of heat exchanger
Life-span.
It is also known that using the solder containing zinc on collecting pipe or tube sheet.Receipts can be greatly reduced in this way
Collector or the corrosion potential on tube sheet surface, thus ideally corrosion potential of the above-mentioned corrosion potential than MPE after being welded
Low, MPE also just can obtain anodic protection by collecting pipe or tube sheet.
But above-mentioned several measures also have shortcoming, i.e., the distribution of zinc is difficult control in welding heat exchanger.Zinc has in aluminium
Especially high diffusion velocity.In welding process in the degree Celsius temperature range of Typical temperature ranges 600, zinc can pass by relatively
Diffusion path farther out, no matter the length of welding process.Between MPE and collecting pipe or can also can in the most adverse case
A large amount of aggregations of zinc are caused inside welding junction between MPE and cooling fins.Thus these welding junctions can turn into heat exchange
Device middle-jiao yang, function of the spleen and stomach polarity most strong region, it means that have the region of minimal erosion potential, and the corrosion that therefore takes the lead in, this may cause
Heat exchanger significantly power attenuation (when the welding junction between MPE and cooling fins corrodes) or even results in heat exchange
Device failure (when the weld between MPE and collecting pipe corrodes).
It is that each should in order to avoid the occurrence of the power attenuation or the even situation of premature failure of this heat exchanger
With no matter respective welding situation, the accurate adjustment of Zn content progress to each part just seems very necessary.But this is very
It is numerous and diverse and cause standard material can not use.

You Xuanwei not be between 0.8 and 3mm, especially between 1.0 and 2.5mm.According to purposes, smaller or bigger final thickness
It is possible or significant.
If needing certain roll hardness state in which final state, such as H14 (DIN EN515), preferably in thick middle
When spending to cold-strip between 300 DEG C and 450 DEG C, a full annealed is carried out between especially 300 DEG C and 400 DEG C.In this
Between thickness depend on required final thickness, pass through the mechanical strength of accurate final rolling degree regulation material.For state H14
For, such as the final rolling degree in the range of 25% to 30%, such as 30%, it is meaningful, to reach under travel position
Intensity and plasticity advantageous combination.On the other hand, usually finally rolling degree only has to the corrosion potential under welded condition
Slight influence does not influence.
For the material in partial annealing state O (DIN EN 515), under final thickness, preferably 300
DEG C and 450 DEG C between, carry out partial annealing when between especially 300 DEG C and 400 DEG C.In addition, methods described is for not exclusively moving back
The material of fiery state preferably carries out homogenizing for ingot blank.Alternatively, moved back by final at a temperature of between 240 DEG C and 350 DEG C
Fire, state H24 can be adjusted out.If having high request to aluminium strip plasticity, particularly with the heat exchanger assembly being made up of the aluminium strip
Production for, then preferred adjustment does well O (also referred to as O Annealed Strips) in the production method of aluminium strip.For the aluminium strip
For application for the production of the pipeline as heat exchanger assembly, especially collecting pipe, preferably adjusted out in production method
State H24 or H14.This state reduction of aluminium strip is used for the punching for the seam that heat exchanger tube is connected.It is well established that ending
Heat treatment such as final annealing or partial annealing have not significant impact for the corrosion potential after welding.
The composition is with the aluminium alloy of the core layer of heat exchanger tube joined components or for the aluminium for the aluminium strip for producing the component
Alloy produces the aluminium alloy of ingot blank of the aluminium strip for casting and has consisting of：
Silicon：Maximum 0.7 weight %, especially preferably 0.10-0.7 weight %, 0.50-0.7 weight %,
Iron：Maximum 0.7 weight %, especially preferably 0.1-0.5 weight %, 0.15-0.40 weight %,
Copper：Maximum 0.10 weight %, preferably at most 0.05 weight %, especially maximum 0.03 weight %,
Manganese：0.9-1.5 weight %, preferably 1.2-1.5 weight %,
Magnesium：Maximum 0.30 weight %, especially preferably 0.01-0.15 weight %, 0.01-0.10 weight %,
Chromium：Maximum 0.25 weight %, preferably 0.10-0.20 weight %
Zinc：Maximum 0.50 weight %, preferably at most 0.25 weight %, especially maximum 0.10 weight %,
Titanium：Maximum 0.25 weight %, preferably at most 0.05 weight %,
Zirconium：Maximum 0.25 weight %, preferably 0.05 weight %,
Inevitable impurity every kind of maximum 0.05 weight %, total maximum 0.15 weight %, remaining is aluminium.
The meaning of every kind of alloy composition is described as follows.
Silicon constitutes so-called α phases (Al with manganese in the fabrication process jointly15Mn4Si2) precipitated phase.It reduce manganese in base
Thus dissolving content in body simultaneously produces influence in the desired direction on corrosion potential, improves machine in addition and by precipitation strength
Tool intensity.Too high content can reduce alloy melting point too strongly.Therefore the silicone content of the aluminium alloy is 0.7 weight % to the maximum.
In order to reach desired corrosion potential simultaneously, the silicone content of the aluminium alloy is preferably 0.1-0.7 weight %, particularly preferred 0.5-
0.7 weight %.
High iron content infringement corrosive nature, is additionally closed, the change of such silicon and manganese in the form of intermetallic phase with silication
The effect for the silicon that compound is described before in being formed just is restricted.Therefore Iron in Aluminium Alloy content is limited in maximum 0.7 weight %,
Preferably even it is limited in 0.40 weight %.In addition, the aluminium alloy preferably has 0.10-0.50 weight %, especially 0.15-0.40
The iron content of weight % scopes.It can cause available raw materials less than the 0.15 weight % iron contents for being even less than 0.10 weight %
The selection of (one-level aluminium and particle) is extremely limited and thus increases the cost of raw material.By 0.10-0.50 weight %,
Especially 0.15-0.40 weight % iron content can be reached between on the one hand good corrosion behavior, another aspect economy especially
Good balance.
Copper greatly pushes the corrosion potential of alloy to forward direction, namely undesirable direction.Therefore the copper of aluminium alloy contains
Amount is limited in maximum 0.10 weight %, preferably even maximum 0.05 weight % inevitable trace.In addition, because copper can
It is diffused into and is welded to connect from core material layer, promotes to corrode especially in angle welding region and in this region, the copper content of alloy
Preferably even drop to maximum 0.03 weight %.
Manganese contributes to intensity to improve.Therefore the manganese content of the aluminium alloy is at least 0.9 weight %.But dissolving manganese is too high
Content push corrosion potential to a undesirable positive direction, thus the content of the aluminium alloy manganese is 1.5 weights to the maximum
Measure %.In particular, the content of manganese matches with the content of the Silicon In Alloys.So manganese is in homogenizing anneal or for hot rolling
In warm and silicon and aluminium constitute intermetallic phase.Thus dissolving manganese content reduction, corrosion potential is moved to desired direction
It is dynamic.Therefore manganese：The ratio of silicon is preferably adjusted to 1.7 to 3 scope, preferably 2 to 3 scope, especially 2 to 2.5 scope.This ratio
Share of the example based on weight %.Manganese content is preferably 1.2 to 1.5 weight %.Good intensity can be reached within this range, together
When can reach sufficiently low corrosion potential again.
Magnesium improves intensity by solution strengthening and pushes corrosion potential to basis, that is, desired direction.So
And the welding behavior (CAB in the higher conventional CAB welding processes of content of magnesium infringement：Controlled Atmosphere
Brazing protective gas soldering).Therefore the content of magnesium is limited in maximum 0.30 weight % in alloy, is preferably even limited in most
Big 0.10 weight %.On the other hand it is well established that by purposefully adding in 0.01-0.15 weight %, especially 0.01-0.10
A small amount of magnesium in the range of weight %, the intensity and corrosion potential of core layer is adjusted, without producing negative shadow to welding behavior
Ring.
Chromium improves intensity and compensates abandoning intentionally to copper at least in part in alloy.But because in higher chromium
Cast layer between undesirable coarse metal can be separated out under content, so the content of chromium is limited in maximum 0.25 weight in alloy
Measure %.It is preferred that chromium content is 0.10 to 0.20 weight %.The strength enhancing that can have been reached within this range is not wished without having
The cast layer occurred is hoped to separate out.
Zn content etching problem caused by foregoing zinc spreads is limited in maximum 0.50 weight % in alloy, preferably exists
0.25 weight % of maximum is particularly preferably even in maximum 0.10 weight %.Because zinc by corrosion potential basis direction on greatly
Ground is promoted, can be with according to need in order to the accurate adjustment low dose of corrosion potential adds zinc, especially in 0.01-0.10 weight ranges
It is interior.
The content of titanium and zirconium in the alloy can be maximum 0.25 weight %.The content of titanium and/or zirconium is preferably
0.05 weight % of maximum.

The heat exchanger, can draw using other feature and advantage with method from explanation next to embodiment,
Referring herein to the figure enclosed.
Shown in figure
A kind of embodiment of the application of Fig. 1 a-b heat exchangers and aluminium alloy or aluminium strip and
Fig. 2 is used for the embodiment for a kind of method that aluminium strip is produced
Embodiment
Fig. 1 a-b show a kind of one embodiment of the application of the heat exchanger and aluminium alloy or aluminium strip.Fig. 1 a are shown
The schematic diagram of the heat exchanger side view, Fig. 1 b show the sectional view for Ib " plane along the mark shown in fig 1 a.
The heat exchanger 10 has multiple heat exchanger tubes 12, and its terminal is connected to the first collecting pipe 14 and the second collecting pipe
16.Thus collecting pipe 14 and 16 turns into the component being connected respectively with heat exchanger tube 12.
Media flow 18 is introduced into the first collecting pipe 14 in use, the media flow is distributed in each heat exchanger tube 12 and finally led to
Cross outflow heat exchanger 10 again of collecting pipe 16.The region of heat exchanger tube 12 second of media flow in use is surrounded, the media flow by
This produces with the outer surface of heat exchanger tube 12 and thermally contacted, and thus reaches the heat exchange between the first and second media flows.In order to increase
For the useable surface area of heat exchange, fin 20 is disposed between heat exchanger tube 12, it welds together with heat exchanger 12 respectively.
Heat exchanger tube 12 is the multi-lumen tube of extruding, and it has multiple passages 22, which thereby enhances the first media flow 18 and heat exchange
Thus the contact area of pipe 12 simultaneously optimizes heat exchange.The heat exchanger tube 12 is made up of low-alloy aluminium alloy, such as the types of EN-AW 3102,
And therefore there is at a fairly low corrosion potential.
Collecting pipe 14,16 has sandwich construction and the solder layer 26 with a core layer 24 and a coating.Extraly,
The etch resistant layer 28 of one layer of coating can be arranged again in the inner side of collecting pipe 14,16.Collecting pipe 14,16 especially can be by one kind plating
Layer aluminium strip is made, and the aluminium strip has corresponding core layer, the solder layer of coating and another layer of painting in the case of possibility in core layer
The structure of the etch resistant layer covered.
Heat exchanger tube 12 is connected together with the hard solder of collecting pipe 14,16, and the material of solder layer 26 is used as solder here.Solder layer 26
It especially can be the aluminium solder alloy of the silicone content with 7 to 12 weight %.
Heat exchanger tube 12 constitutes coupling electroplating system with collecting pipe 14,16 in this way.Heat exchange of the prior art
Occur that a problem, i.e. heat exchanger tube can be by corroding especially big influenceed due to its low corrosion potential on device, it is thus possible to carry
Before leak.This problem is solved on heat exchanger 10, and mode is to use the aluminium alloy with following composition as collecting pipe
14,16 core layer 24：

Magnesium：Maximum 0.10 weight %, especially 0.01-0.10 weight %,
Chromium：0.10 to 0.20 weight %,
Zinc：0.10 weight % of maximum,
Titanium：0.25 weight % of maximum,
Zirconium：0.25 weight % of maximum,
Inevitable impurity every kind of maximum 0.05 weight %, total maximum 0.15 weight %, remaining is aluminium.
Being constituted using this alloy can reach that following effect, i.e. core layer 24 have the corrosion electricity lower than heat exchanger tube 12
Gesture, thus the latter anodic protection is obtained by collecting pipe 14,16.
If heat exchanger 10 is in the environment for easily promoting corrosion, such as in automobile engine nacelle, so corrode first
Appear in collecting pipe 14,16 and may in the case of on fin 20, and vital for the operation of heat exchanger 10 change
Heat pipe 12 only can be by slight erosion.The service life of so heat exchanger 10 is extended.
The anodic protection of the exchange heat pipe 12 provided by collecting pipe 14,16, can especially abandon the solder containing zinc, this
Solder is partially used as the anticorrosive protection of heat exchanger tube in the prior art.The aluminium alloy of solder layer 26 correspondingly preferably has most
Big 0.50 weight % Zn content, particularly preferred maximum 0.20 weight %.So avoid unmanageable zinc in heat exchanger

Homogenized under part.Homogenization step 82 can also be saved in an alternative of this method.
When needing production coating aluminium strip, solder layer and/or etch resistant layer are such as carried, is used as in following step 84
The ingot blank and the one or more coating of the core layer above or below that are placed in for core layer produce plating stack.Each plating
The thickness of layer is respectively 5% to the 20% of the plating stack gross thickness.
Hot rolling, the especially thickness to 3-7mm scopes are carried out to the ingot blank or the plating stack in following step 86.
The ingot blank or the plating stack are preheated before hot rolling, 450 DEG C -480 DEG C of temperature model is specifically preferably preheated to
Enclose retention time interior and that 3-10 hours are kept under target temperature.
To may in the case of the hot-rolled band of rolling covering carried out in following step 88 cold rolling, preferably arrived to 1.0
2.5 final thickness.When carrying out cold rolling, can in interior thickness in intermediate steps 90 carry out intermediate annealing (recrystallization is moved back
Fire), preferably in 300 DEG C to 400 DEG C temperature ranges.
Final annealing can be optionally carried out again in following step 92 being cold-rolled to after final thickness.Pass through
Partial annealing in 300-400 DEG C of temperature range can obtain the material in partial annealing state O by this method.
Alternatively, a final annealing can also be carried out in 240-350 DEG C of temperature range for the material in H24 states.

Electricity compatibility.In order to examine this electricity compatibility to carry out contact corrosion measurement according to DIN 50919.In order to carry out the measurement
Sample A, B and C is allowed to be contacted respectively in a kind of electrolyte with the sample K being made of alloys in common use EN-AW 3102 extruded tube.
The acidifying synthesis according to examination criteria ASTM G85, Annex A3 pH value between 2.8 to 3.0 is used as electrolyte
Seawater.Sample A, B, C and K carry out above-mentioned welding analog respectively before carrying out the measurements.According to ASTM G69, EN-AW 3102 makes
Into sample K under welding analog state have -742mV corrosion potential.
Aspect is not plated in sample A, B and C according to DIN 50919 contact corrosion measurement, that is to say, that directly in core
Carried out on layer.According to surveying, sense of current is compatible to electricity to be evaluated respectively.When electric current is from representing heat exchanger assembly, such as
The sample of tube sheet or collecting pipe flows to heat exchange tube material, especially MPE, then just with compatibility.In this case should
Component (tube sheet/collecting pipe) is preferentially decomposed, and sacrifices itself to protect heat exchanger tube (MPE).
In contact corrosion measurement, the mass loss that sample A (O Annealed Strips) and sample K combination obtains sample K is
1.6g/m2, the mass loss that the combining of sample B (O Annealed Strips) and sample K obtains sample K is 3.9g/m2.On the other hand, sample
The mass loss that product C (O Annealed Strips) and sample K combination obtains sample K is 34.4g/m2.Thus, sample A and B are compared with right
There is substantially preferably electricity compatibility to sample K than sample C, that is to say, that sample K corrosion passes through the group with sample A or B
Conjunction is dramatically reduced.
Generally speaking, afore-mentioned test is illustrated by using above recommendation as the component core layer being connected with heat exchanger tube
Alloy can reach the anodic protection of exchange heat pipe, so that the service life of heat exchanger is greatly prolonged.In addition corresponding group
Part also has enough intensity.
